He wanders the stairs. His sense of physical coordinates informs him of the tricks they're pulling - seamlessly changing his elevation, transporting him directly to stairwells in different parts of the building when he takes a connecting door. Some of the doors lead to closets instead, for variety. There is a general absence of windows.
He doesn't know enough about matter manipulation or transport magic to think of any obvious solutions right away, so when he gets bored, he sends a finding spell - one that can pass through solid matter - to locate the nearest roof, and teleports onto it.
"Yep," he says, mostly to himself, but still in Leraal as a local default. "Those sure are some messed-up stairs."
He flops down at the edge of the roof and peers over it at whatever might be going on down below.
For lack of anything much better to do, he watches the ducks. They are sparkly.
He wonders what eating is like.
Well, there's a pond right there, but - <Hey, Keo, is there food around here?>
<I can eat most things,> he says. <That was my dormant form you saw before; in my human form I have pretty much the usual set of human functions and systems, just - not so biological. More input leeway and cleaner energy conversion. Wait, what other species go to school here? Do you have magic talking ducks in this world or something?>
<...Well, I've heard of humans,> he says, giggling to himself. <Whatever. I can pretty much eat anything that's made of matter, as far as I know. I might have trouble if it was strongly corrosive or something. Where do I go to get a cafeteria pass?>
"...You don't recognize me, do you," he says, amused. "Last time we talked, I was about this big—" and he indicates with his hands the size of the Bicycle pack that his dormant form mimics.
"Hey, it's okay. I mean, I'm okay, now. Your - mom? Is she your mom? - really helped me out. Totally worth the meltdown."
